Queen Mother's A Scientist

Liang Wensheng recovered and looked at the glass on Su Shaowen's blowpipe.

He passed away with a flash of amazement on his face. Then he approached a few steps, looked very carefully, and exclaimed, "is this a success? There is no bubble. It's really as clear as the master said. It's completely transparent! Shaowen, you're great! "

Su Shaowen pursed his mouth and smiled shyly. Obviously, he was also very happy.

"I'll tell the master!" Liang Wensheng was overjoyed and turned and ran out!

"Elder martial brother..." Su Shaowen opened his mouth to stop him, but Liang Wensheng ran too fast and ran out for a long time.

Su Shaowen looked down at the blowpipe in his hand and was filled with a sense of achievement. He decided to try again to make better glassware.

He carefully peeled off the cooling glass on the blowpipe and put it on the partition aside.

Many glassware have been placed on the partition board in various forms, all of which were made by Su Shaowen during his experiment.

He has been trying different strengths and angles to see what shape or radian he can blow. This glass is his most satisfactory work at present.

Su Shaowen put the glass on it. As soon as he let go, he suddenly gave a bang——

The glass exploded!

There was a gap at the bottom of the cup, and the splashing glass slag cut Su Shaowen's fingers, leaving a shallow red mark.

Su Shaowen was stunned and stared at the broken glass.

How happy it was, how disappointed it is now

He thought of staying by the furnace day and night and constantly trying to figure out various skills of blowing glass. He thought of sweating and prickly heat from the furnace and itching so that he couldn't sleep all night. He thought that his mouth was numb and didn't dare to relax!

Because he's scared

Afraid that he will be sent back by Hua Qingxue if he appears incompetent.

He knew that he was clumsy and didn't like master song. He became an apprentice to master song for a year, but he always did chores and coolies in the workshop.

Master song disliked him for being too short and thin, and Shiniang also thought he was not pleasing.

He wanted to learn how to make glass, so he secretly collected the leftover materials left by the master and senior brother when making glass. As a result, he was found and immediately beat and scolded.

It's like a dream for him to stay in the firearm camp to make glass. Therefore, he must not lose this job!

Su Shaowen bit his lip, turned to get a broom dustpan, cleaned silently, and then began to make new glass.

He must succeed.

……

Hua Qingxue follows Liang Wensheng to the glass workshop of the firearm camp. As soon as she enters the door, she sees a pile of broken glass slag by the door.

Su Shaowen wiped the sweat on his face and turned around with a smile. "Master, wait a moment, I'll be right away."

He said, then turned back and continued to work by the furnace.

Liang Wensheng ran to the shelf next to the wall. Instead of finding the glass made by Su Shaowen, he found a row of broken glassware. Although some had no holes, there were cracks on the bottle.

"What's going on?" He was surprised and looked at Su Shaowen.

Hua Qingxue also looked at a loss.

Su Shaowen came slowly with the blowpipe in his hand, and his face was nervous. "This time, it will not break... It will not break..."

However, God seemed to deliberately joke with him. When Su Shaowen gently put down his glass and thought it was safe, a soft voice suddenly sounded——

Click, click.

The smooth cup wall cracks a fine crack, like a hair falling on it, which is very eye-catching.

Su Shaowen's eyes finally turned red. He clenched his lips and looked at the cracked cup. His face was unwilling.

"Master, i... I don't know why..." Su Shaowen hung his head and looked at the pipe in his hand. His face was depressed and annoyed. He was very helpless.

Liang Wensheng was very sorry when he saw it. He couldn't help saying, "master, Shaowen really made the kind of glass you want. I saw it with my own eyes. There's no impurity at all! No bubbles! Shaowen works hard every day. In the firearm camp, he always goes to bed last and gets up first... "

Hua Qingxue didn't seem to be listening at all. She stared at the crack on the glass wall and looked thoughtful.

"That... Master?..." Liang Wensheng gave a tentative cry.

"Ah!" Hua Qingxue suddenly shouted, clapping his hands with a sound, "I know what's going on!"

Liang Wensheng and Su Shaowen looked at each other and were confused.

Su Shaowen whispered, "master, do you know the reason why the glass is cracked?"

Hua Qingxue's face reddened slightly and seemed embarrassed. "It's my fault. I forgot to tell you that the last step in making glass is annealing. Glass without annealing is very easy to crack, which is also called cold explosion."

"Annealing?" Su Shaowen asked, "what is annealing?"

"Annealing is to keep the glass products warm or cool down slowly for a period of time after the glass products are completed, so as to reduce the thermal stress in the glass." Hua Qingxue picked up the cracked glass and explained with Su Shaowen, "the glass has undergone fierce temperature changes and shape changes in the forming process. This change has left thermal stress in the glass, which will reduce the strength and stability of the glass products. At this time, if the temperature drops suddenly, it is likely to break, so the glass products must be annealed after forming."

Su Shaowen stared at the glass in her hand, "that is to say... I didn't do anything wrong? There is no problem with my blowing method? "

"Yes." Hua Qingxue smiled slightly and touched Su Shaowen's head. "You did a good job. It's just one step less."

Su Shaowen was relieved and finally had a smile on his face. "Master, I'll do it again. I'll remember it this time."

Hua Qingxue shook his head, "don't do it."

Su Shaowen's heart suddenly hung up when he heard the speech!

He looked at Xianghua Qingxue uneasily. His eyes showed panic. He was worried that Hua Qingxue didn't think he was smart enough and didn't want him

Hua Qingxue pondered for a moment and said, "you have to make something else for me first..."

Su Shaowen hung his heart, and then put it down. He asked cautiously, "what does the master want me to do?"

"I'm going to Shengjing with the general in a few days. I want to make some mirrors as gifts to Shengjing's friends." Hua Qingxue looks at Liang Wensheng and says with a smile, "you two need to help with this."

Liang Wensheng looked at Su Shaowen and Hua Qingxue, "er... Master, Shaowen and I can't make mirrors..."

"You help me prepare tin foil and mercury. Shaowen makes glass of the same size according to the size of the mirror we usually use." Hua Qingxue thought about it and added, "... Ah, by the way, we need to find some craftsmen who are good at carving to help us inlay the back of the mirror and carve some auspicious patterns."

To make a thin and flat glass plate, Su Shaowen is competent after this period of practice.

There are ready-made molds for making glass plates in the workshop. You only need to inject a thin layer of glass frit and peel the mold after standing and cooling.

It's just thin and brittle. How can you make a mirror?

Liang Wensheng imagined a bronze mirror inlaid with glass in his mind. How do you think and feel strange

They prepared according to Hua Qingxue's requirements. In the next time, Hua Qingxue gave them a chemistry class, focusing on the chemical reaction process after the encounter of mercury and tin.

Just stick shiny tin foil on the glass surface and pour mercury. Mercury is a liquid metal. It can dissolve tin and wait quietly until the two merge into a viscous silvery white liquid, which is tightly attached to the glass plate, and the mirror is completed.

"The principle of the mirror is that it can reflect light. In fact, the ability of mercury coated mirrors to reflect light is not very strong, but with our current conditions, it is also a great success."

Hua Qingxue looked at the mirror in the static reaction in the mold, with a faint smile on his face and relaxed tone, "when we make a distiller and can refine silver nitrate, we will have a more convenient way to make a better mirror."

Although Su Shaowen has been making glass for some time, this chemical knowledge is his first contact. He listens very carefully. The more he listens, the more he admires the light snow in China.

"Master, you are really good. You can do anything." Su Shaowen said sincerely.

Compared with master song's stinginess, Hua Qingxue has no reservations about him and is willing to teach him no matter what problems.

Liang Wensheng is actually one year older than Hua Qingxue. He also worships Hua Qingxue, "yes! Master, nothing can defeat you! "

Hua Qingxue smiled at the speech. "In fact, it's very simple. When you get familiar with these knowledge in the future, you will understand that in fact, everything in our world is composed of elements. As long as you understand the characteristics of these elements and carry out artificial combination, you will get the effect we want."

She picked up the semi-finished glassware made by Su Shaowen and said, "for example, this glass is a transparent and fragile object in the eyes of ordinary people, but in my eyes, it is only silica."

She put down the glass and picked up Su Shaowen's porcelain cup for drinking water. "What's this? A cup, but for me, it's a silicoaluminate compound. The main component is aluminum oxide. "

Liang Wensheng suddenly realized, "no wonder the master asked us to recite the chemical element list in order to make us better understand the constituent elements of these living objects!"

Hua Qingxue nodded with a smile, "there is no shortcut to learn chemistry. After reciting the element list, we can know and understand the characteristics of each element one by one. But now our conditions are limited and we can't teach you one by one..."

After all, it is not modern. Many chemicals can be bought directly, such as silver nitrate, which is generally sold by pharmaceutical companies and of any purity.

But here, huaqingxue can only find a way to extract it by herself.

There are also some elements that were extremely rare in ancient times and could hardly be found.

But how to say... Although it's difficult, watching Liang Wensheng and Su Shaowen seriously exchange each other's understanding and views on elements, Hua Qingxue's sense of achievement arises spontaneously.

She felt that she had done a good thing, and the unexpected crossing seemed to become meaningful.
